Description

Best 12v 55/60w Koito Japan H4 halogen headlight bulb

• Bulb Type: H4 (P43t base) – A dual-filament bulb that powers both High Beam and Low Beam from a single unit.
• Voltage/Wattage: 12V 60/55W. It draws 60W for high beams and 55W for low beams, the legal standard for road use worldwide.
• Color Temperature: Approx. 3200K (Warm White/Yellowish). This spectrum is preferred for its ability to cut through adverse weather like heavy rain, fog, and dust.
• Origin: Made in Japan, ensuring world-class quality control and filament alignment.

• Precision Filament Alignment: Koito is famous for its strict manufacturing tolerances. The filaments are placed with sub-millimetre precision to ensure the beam pattern matches the headlight’s optics perfectly, preventing glare for other drivers.
• Superior Durability: Built with high-strength hard glass and vibration-resistant filaments, these bulbs are designed to survive the harsh “shaking” of rough roads.
• UV-Filter Technology: The glass is treated to filter UV rays, protecting your vehicle’s plastic (polycarbonate) headlight lenses from premature yellowing or clouding.
• Consistent Output: Unlike cheaper alternatives, Koito bulbs maintain a steady lumen output throughout their lifespan, which typically ranges from 500 to 1,000 hours.
